This webinar will provide a brief background on TMDLs and MS4 permits as regulatory drivers for stream restoration. Presenters will discuss approaches from the Chesapeake Bay Program and Maryland Department of Environment as examples to illustrate how stream restoration crediting are used to help meet TMDL and MS4 permit objectives.
Participants will learn the basic steps to compute nutrient and sediment load reductions credits using the most recent Chesapeake Bay Expert Panel Protocol methodology, and how to compute equivalent impervious area credits following Maryland’s June 2020 guidelines. Topics will include data collection needs, applicability and limitations, and recent revisions to the guidelines. Example computations and resources will be provided.
At the end of this presentation, participants will be able to:
- Explain regulatory drivers for stream restoration including TMDL and MS4 permits.
- Locate resources provided in the presentation to evaluate local regulations and TMDLs.
- Describe the Chesapeake Bay TMDL Protocols for computing nutrient and sediment load reductions for urban stream restoration.
- Use resources provided in the presentation to further understand and perform computations.
- Understand how to compute equivalent impervious acre credits for stream restoration following MDE 2020 guidance.
The webinar will be held on December 17th, 2020, from 12:00 PM to 1:15 PM EDT. 1 PDH hour will be available for attendees. As space is limited, please register here.
